AirDog Pump Kits & Components

When it comes to diesel fuel, one factor that affects the quality of the fuel and the performance of your truck, is trapped air. As you drive your truck the sloshing and pumping of the fuel in the tank causes agitation which causes air bubbles to be trapped in the fuel. In your standard vacuum-feed filter systems on diesel trucks there is no way to separate the air from the fuel. The higher the volume of agitation, the more air bubbles and the less your engine’s transfer pump is able to deliver pure fuel.

Conventional fuel filter systems do not address the issue of filtering out the air in the fuel, and in fact can add to the problem by restricting the flow of the fuel, causing the agitation to increase. Not only does this decrease fuel efficiency, but it can also be harmful to your injectors.

Some of the benefits of the Airdog system include:

Removal of air and vapor from your diesel fuel

High flow-rate of fuel to your engine

Longer injector life

Increased injection pump life

Increased diesel fuel economy

Optimized engine performance

Increased torque output

Improved throttle response

The AirDog Fuel Preporator is the only system in the world that allows you to get air-free fuel at the correct pressure for incredible fuel efficiency in your diesel truck.

1) The AirDog Fuel Preporator receives vacuumed fuel from the fuel tank which contains the trapped air, particulate contaminates and various amounts of moisture.

2) The fuel then passes through the water separator portion of the device which removes the water and large particulate contaminates that could cause damage to the gearator fuel pump.

3) With only entrained air/vapor and tiny particulate contaminates remaining, the fuel then enters the fuel pump.

4) Now with correct positive pressure applied, the fuel enters the filter. The fuel is then filtered from remaining particulates and contaminates and the trapped air is separated. Through the positive fuel air separation features of the patented Fuel Preporator, the separated air is discharged from the filter through the Primary Air/Vapor Discharge Port and into the return to tank passage after the regulator.

5) The fuel then passes into the high pressure injection system of your engine.

6) Any excess fuel that is not needed by the engine is released through the pressure regulator, combined with the air and foam, and returns it to the fuel tank. The regulator controls the fuel pressure to the engine.

Choosing the right AirDog Fuel Preporator system that’s right for your truck depends on several factors.

HORSEPOWER

Once you’ve sorted which AirDog products are right for your truck’s year and make, you’ll need to choose the right one according to the amount of horsepower you truck has.

For trucks with up to 500HP, we recommend using the AirDog® and AirDog® II 100 units.

What is the difference between and AirDog® and AirDog II®?

While both the AirDog and AirDog II offer you the same unique air filtration system, the AirDog II has some improvements from its predecessor that push it farther along in providing you the best system on the market. In addition to having an adjustable regulator, the AirDog II also has a redesigned pump assembly, created with a dual inlet design that allows more fuel to flow into the Gerotor, allowing increased pump volume without extra strain.

Additionally, the AirDog II has an improved base which redirects the pressurized fuel through passageways, allowing more fuel to be stored in the filters and thus creating a much better on-demand system.

For those trucks in the 500-800HP range, AirDog® 150 and AirDog® II 165 units are recommended.

What’s the difference between the AirDog 150 and the AirDog II 165?

The physical unit of the AirDog 100 and AirDog 150 are the exact same size. However, the difference lies in the flow and RPM range. In the AirDog® 100, there is a 2000 r.p.m. motor and it has a flow rate of 100 gallons, whereas the AirDog® 150 uses a 3000 r.p.m. motor and has a flow rate of 150 gallons per hour.
